Hello,
I've found that rename() cannot replace the file
which is opened with writable access on Cygwin.
On Linux, it works.
If I understand correctly, it should work under POSIX.
Here's sample code for reproduce.
---
#define OLDPATH "oldpath"
#define NEWPATH "newpath"
int main () {
int fd;
struct flock fl;
char buff[] = "test";
fd = open (OLDPATH, O_CREAT | O_RDWR | O_TRUNC, 0666);
close (fd);
fd = open (NEWPATH, O_CREAT | O_RDWR | O_TRUNC, 0666);
if (rename (OLDPATH, NEWPATH) < 0) perror ("rename");

What are you trying to do by renaming the oldfile
over the top of a still-open-for-write, "newfile".
Why rename over the top of another file? What are you trying
to do? Maybe there is a better way to do it? ;-).
